The wishbone design splits into two runs at the rear of the trailer, each independently color-coded so tail lamps, stop\/turn signals, and an auxiliary circuit can all be wired without splicing extra wire into the main harness. A 4-foot trunk connector extends the main run forward, making it easier to route the harness from the tow vehicle connector back to the trailer frame.\u003c\/p\u003e\u003cp\u003eEach of the five conductors has a specific function: white for ground, brown for tail lamps, yellow for the driver side stop\/turn signal, green for the passenger side stop\/turn signal, and blue for auxiliary use such as additional lighting or a brake circuit. This color coding matches standard trailer wiring conventions, so the A25WH can be used as a direct wire-for-wire replacement on trailers already following that scheme. The harness is constructed of wire suited for trailer wiring applications and ships in retail clamshell packaging, making it easy to identify and install as a complete replacement harness rather than sourcing individual wire runs.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Optronics\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e A25WH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHarness Length:\u003c\/strong\u003e 25 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrunk Connector Length:\u003c\/strong\u003e 4 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Configuration:\u003c\/strong\u003e 5-way (5-conductor) wishbone split harness\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWire Colors and Functions:\u003c\/strong\u003e White - Ground;
